Its prevailed color is blue, whence its name, but varying from a fine Prussian blue to sky-blue, or bluish white. It occurs also of various shades of green, and even gray, or white and reddish. It is infusible by the common blowpipe. This mineral is called by Hauy and Brongniart, disthene, and by Saussure, sappare.
